"The two leaders discussed ways to de-escalate the situation in Gaza, and President Obama underscored the necessity of Hamas ending rocket fire into Israel. President Obama also offered condolences for the terrible loss of life in the recent train accident in Egypt.

"President Obama then called Prime Minister (Benjamin) Netanyahu of Israel, and received an update on the situation in Gaza and Israel.

"In both calls, President Obama expressed regret for the loss of Israeli and Palestinian civilian lives, and agreed to stay in close touch with both leaders."
